3 megaplex-4100 Next-Generation Multiservice Access Node m u l t i p l e x e r s transports voice, data and advanced ethernet services over pdh/sdh/sonet networks stm-1/oc-3 next-generation standard ADm or terminal 4/1/0 non-blocking cross connect of up to 1.1 Gbps (160 mbps tdm plus 1 Gbps ethernet) up to four stm-1/oc-3 ports up to four Gbe ports shdsl access platform with up to 80 shdsl ports up to 80 e1/t1 ports up to 30 Fast ethernet ports up to 120 n x 64 kbps or sub-ds0 rate data ports up to 160 analog voice ports supports selected megaplex-2100 i/o modules modular 4u-high, 19-inch unit with 10 slots for i/o modules sfp optional for stm-1/oc-3, Gbe and Fast ethernet ports The Megaplex-4100 is a high capacity multiservice concentrator supporting access over PDH/SDH/SONET transport networks. Large organizations with SDH/SONET backbones require an efficient way to transport and provision multiple user channels of various services over their high capacity pipes. The termination and aggregation of pure Ethernet traffic makes the Megaplex-4100 a highly effective IP/MPLS aggregator as well as a tool to better utilize the SDH/SONET bandwidth by supporting VCAT. The Megaplex-4100 does this with a large range of multiport modules that support Ethernet-based Fast Ethernet and Gigabit Ethernet services, in addition to TDMbased services, such as dedicated low speed n x 64 kbps data, high speed data (up to STM-1/OC-3), digital voice, analog voice, and ISDN. Its ability to handle a broad range of Ethernet, data and voice services and various network technologies in a single compact managed node makes the Megaplex-4100 a versatile and cost-effective next-generation multiservice access node solution. Next-generation ADm/terminal STM-1/OC-3 private network owners can prolong the use of existing equipment or terminal multiplexers, saving replacement or expansion costs, by implementing VCAT protocols to carry the Ethernet traffic in a more efficient way and minimize wasted bandwidth. Megaplex-4100 supports STM-1/OC-3 add/drop multiplexing for grooming LAN and legacy (TDM) traffic over SDH/SONET networks. Ethernet traffic can be mapped into one VC-4, up to three VC-3/STS-1, or up to 63 VC-12 or 84 VT MSP/APS redundancy is supported. The Megaplex-4100 brings Ethernet economics and packet switching efficiency to existing SDH/ SONET/TDM infrastructures. It thereby enables utilities and other private fiber network owners to reduce both operating and capital expenditures as they use their optical bandwidth for reselling revenue generating Ethernet services. For a modest investment, new business opportunities can be realized by leveraging existing equipment to support clear channel data streams and the latest high bandwidth services. ethernet aggregator The Megaplex-4100 can terminate Ethernet traffic carried over links, or a bundle of lines, as well as IDSL, SHDSL or VCG in the STM-1/OC-3. This traffic can then be switched either to a different PDH/TDM trunk or to the Fast Ethernet or Gigabit Ethernet ports. Ethernet CPE can also be connected via SFP or UTP ports of the Megaplex-4100 Fast Ethernet or GbE, and cross connected with other services. Various users can benefit from this solution: SDH/SONET users who need to extend their network lifecycle by maximizing bandwidth; users with mixed services (Ethernet and TDM); users who do not need IP connectivity or services at this time but would like to invest in a solution that will enable a migration path; and users with two networks SDH/SONET for voice and MPLS/IP for data. 4/1/0 Ds0 cross connect Megaplex-4100 features an internal 4/1/0 cross connect matrix of up to 160 Mbps. Traffic from any channel can be cross connected directly to any other channel. Ethernet traffic carried over copper, DSL or fiber can be either cross connected to another TDM/PDH trunk or terminated by the packet bus. Traffic from the STM-1/OC-3 channel can be either cross connected to another STM-1/OC-3 channel on a VC-12/3 level or with any other channel. These capabilities enable the Megaplex-4100 to function as a service differentiation point at the headquarters, handing off traditional voice and data services to the transport network. At the remote offices or customer premises, the Megaplex-4100 may also be deployed to effectively fan out multiple voice and data services. multifunction node Enterprises, campuses and utility companies can deploy two, three or even four different units in order to create an edge to the STM-1/ OC-3 ring; multiplex voice, fax, data, and other low speed traffic; groom and cross connect between channels; and terminate Ethernet traffic. The Megaplex-4100 can also work opposite devices like Teleprotection modems and Omnibus units. 86 RAD Data Communications 2009 Catalog

14 prbm-20 Signaling Monitoring Probe RAD s PRBm-20 probe is a cost-effective method for centralizing network management and reducing traffic monitoring costs. Rather than installing expensive analyzers at small and medium-sized locations or sending management information from each line over a separate link, the PRBm-20 concentrates up to 31 signaling timeslots and sends them to a central protocol analyzer over a fully utilized link. Cuts Opex for maintaining services The PRBm-20 reduces the cost of ownership of advanced, revenue-generating services, such as SMS messaging, instant messaging, call forwarding, voic and international roaming, by collecting signaling timeslots from many leased lines and grooming them over a full link to the protocol analyzer at the central site. reduces leased line costs The PRBm-20 extracts the signaling timeslots from up to eight links and grooms them onto one or fractional output line. By extracting any of the signaling timeslots from the traffic, the PRBm-20 reduces the number of lines required to connect to the protocol analyzer. improves network performance Service providers use the data from the signaling timeslots to monitor the quality of the connection and to detect network faults. PRBm-20 cost-effectively transports signaling information, enabling the service provider to assure quality of service (QoS) at a competitive price. Complementary solution The PRBm-20 can be used to expand any existing monitoring method. It seamlessly integrates with any T-connector or patch panel used to divert the timeslots, and with any standards-based protocol analyzer. The PRBm-20 non-modular, standalone, probe is the latest low-end addition to RAD s signaling monitoring solutions. RAD offers a range of signaling monitoring devices, transporting signaling timeslots from links at speeds of up to STM-1 fiber optic links (see DXC family, pages ).

Plug-in interface modules can accommodate up to eight links each (see Modules section on page 100). Many services are supported, including n x 56/64 kbps, ISDN,, T1, E3, T3, and STM-1. Cross connect, groomer and broadcast All DXC modules allow maximum flexibility between ports. A user-programmable connection matrix connects any incoming 56/64 kbps timeslot to any outgoing 56/64 kbps timeslot. It supports cross connect functions, such as drop-and-insert, distribute and collect. The DXC family enables the grooming of fractional traffic from the user side into full / T1, E3/T3 or STM-1 trunks, for connection to the network. Grooming and bandwidth maximization are implemented by placing the n x 56/64 kbps data channels into an or T1 frame (including internal of the E3 or T3 modules or VC-12 containers of the STM-1 module), using only the required number of timeslots. This provides fractional CSU/DSU functionality. The DXC family can broadcast any traffic combination from a single input to numerous destinations. Channel relocating and half duplex conferencing are also supported. e1/t1 converter The DXC family is also capable of converting between ports. A-law/µ-law and signaling conversion are performed according to and T1 standards. DXC-8R, DXC-10A and DXC-30 convert up to 16 ports. T1 traffic can be directly extracted from the STM-1 module (which can act as a converter for up to 30 T1 links). e3, t3 and stm-1 multiplexer modules These modules provide full channelization functionality for the multiplexing and demultiplexing of DS0 traffic. Aggregated payload is 34 Mbps for E3; 45 Mbps for T3; and the equivalent of 61 Mbps for STM-1 (one chassis). When chaining a number of units, the aggregated payload is equivalent to 155 Mbps. G.747 is supported by DXC-100 (see page 102). redundancy The DXC family provides flexible redundancy and protection to accommodate each user s needs and help minimize service downtime.

26 FCD-ipl and Fractional Access Unit with Integrated IP The FCD-IPL is a customer-located demarcation router for transporting 10/100BaseT Ethernet traffic over or fractional links. It is ideal for supporting large-scale rollouts of Layer 3 VPN services over lines to small and mediumsized enterprises (SMEs). The FCD-IPL comes with an integrated IP router supporting PPP. The internal IP router operates in two modes: standard IP routing based on static entries, RIP-1 and RIP-2; and transparent IP, in which frames received via the LAN/WAN interface are routed to the other interface, with the exception of management traffic, which is sent to the FCD-IPL host IP address. Qos differentiation for Voip, video and data The FCD-IPL transports Ethernet traffic at wire speed, enabling full use of the 2 Mbps link. The IEEE compliant 10/100BaseT user port supports auto-negotiation and operates in both full and half duplex modes.
